20180707 | MD_CalvertCliffs_1 | CONTROL ROOM VENTILATION INOPERABLE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53493

"At 0242 EDT, the CCNPP (dual unit, single control room) control room supply damper failed shut. This rendered the Unit 1 and Unit 2 control room ventilation inoperable and the appropriate LCOs were entered.

"At 0249, control room ventilation was restored to service and the appropriate LCOs were exited. This is being reported under 10 CFR 50.72(b)(3)(v)(D)."

The licensee notified the NRC Resident Inspector.

----------- [ Current event for IL_Byron_2 ]

20180706 | IL_Byron_2 | TRANSFORMER FAILURE CAUSES LOSS OF OFFSITE POWER TO UNIT 2 |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53491

"At 1201 [CDT], Station Auxiliary Transformer 242-2 experienced a bushing failure, resulting in a loss of offsite power to Unit 2.

The 2A and 2B Diesel Generators started and sequenced loads onto the Unit 2 ESF buses appropriately.

All other buses normally powered from the Station Auxiliary Transformers automatically transferred to the Unit Auxiliary Transformers.

ESF Bus 241 and 242 Undervoltage Relays actuated to start the Diesel Generators and the 2A Auxiliary Feedwater Pump started on the 2A Diesel Generator sequencer.

ESF Battery Charger 212 tripped at the same time, which was an unexpected condition. DC Bus 212 was cross-tied with DC Bus 112.

"This notification is being made under 10 CFR 50.72(b)3(iv)(A) due to the actuation of both Unit 2 Diesel Generators and the 2A Auxiliary Feedwater Pump.

"The NRC Senior Resident Inspector has been notified."

Currently, offsite power was restored via the Unit 1 Unit Auxiliary Transformer.

Both Unit 2 Emergency Diesel Generators have been secured.

DC Busses are still cross-tied.

The licensee is currently in a 72-hour shutdown action statement for the loss of offsite power and a 7-day action statement for having the Unit 2 DC Bus cross-tied to Unit 1.
